binutils/ChangeLog

	* dlltool.c (set_dll_name_from_def):  Accept new second arg that
	indicates if we are building DLL or EXE, and use it to add a
	default suffix to the output filename when none is already present.
	(def_name):  Indicate we are building an EXE when calling it.
	(def_library):  Indicate we are building a DLL when calling it.

ld/testsuite/ChangeLog

	* ld-cygwin/exe-export.exp:  Add "-lkernel32" when linking test exe.
	* ld-cygwin/testexe.c (testexe_main):  Indicate whether global_a
	was set to correct final value using error return status.
	(testexe_dummy):  Dummy function calls an import from kernel32.dll
	to ensure it is mapped into the process space at runtime.
